If you want to dig deeper and learn other cool things you can do with the HttpClient – head on over to the main Apache HttpClient tutorial. Basic User Authentication using HttpClient This is a simple example uses HttpClient to execute an HTTP request against a target site that requires user authentication. The following examples show how to use org.apache.http.client.methods.HttpGet#setHeader.These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.
We have learned about building RESTful webservices already. Now learn to build a JAX-RS REST client for consuming the webservices using HttpClient RESTful Client.
I will be reusing the code written for jaxrs xml example.
The HTTP GET and POST REST APIs which I will be accessing are as defined.
To build a RESTful client using apache httpclient, follow below instruction.

Httpclient Execute
The GET method is used to retrieve information from the given server using a given URI. Requests using GET should only retrieve data and should have no other effect on the data.
Apache Httpget Timeout
The HttpClient API provides a class named HttpGet which represents the get request method.
Follow the steps given below to send a get request using HttpClient library
Step 1 - Create a HttpClient object
The createDefault() method of the HttpClients class returns a CloseableHttpClient object, which is the base implementation of the HttpClient interface.
Using this method, create an HttpClient object as shown below −
Step 2 - Create an HttpGet Object
The HttpGet class represents the HTTPGET request which retrieves the information of the given server using a URI.
Create a HTTP GET request by instantiating this class. The constructor of this class acceptsa String value representing the URI.
Step 3 - Execute the Get Request
The execute() method of the CloseableHttpClient class accepts a HttpUriRequest(interface) object (i.e. HttpGet, HttpPost, HttpPut, HttpHead etc.) and returns a responseobject.
Execute the request using this method as shown below −
Example
Following is an example which demonstrates the execution of the HTTP GET request using HttpClient library.
Output
The above program generates the following output −
